Burning was a common means of disposing of a <i>prize</i> <a href="https://en.wikipedia.org/wiki/Prize_(law)" rel="nofollow">https://en.wikipedia.org/wiki/Prize_(law)</a> by naval forces, privateers, or pirates, when for whatever reason the victorious force decided manning the prize and sending it to a friendly port was not practical. Reasons could be some combination of 1) the victor already was short-crewed 2) the vessel was too damaged by a battle 3) the most valuable cargo had been transferred at sea to the victor 4) reaching a friendly port was not practical 5) the economic value of the prize did not justify sending to port.<p>So this could have been 1) from the war of 1812 2) US or British operations against Caribbean pirates in the 1820s 3) a slaver, captured by British or US naval forces anytime after the war of 1812 4) a Union vessel captured by Confederate forces or a blockade runner captured by Union forces during the Civil War.
I don’t think 2109 or 9012 could be a year in any of the world’s calendar systems. So, were rudders factor-produced, with serial numbers, or does that number apply to the ship?
